Whatsup guys, I've installed correctly Yosemite Niresh version 10.10 (not 10.10.1 because 10.10 is for UEFI, and my motherboard is UEFI) and I've some problems:

-HDMI audio not working (I've tried a lot of methods, fix and many other workarounds.. but anything fix HDMI audio, Now Im using speaker through green-jack

-Niresh Sierra wont update Niresh Yosemite ()

-on Niresh Yosemite 10.10.1 in the past I've installed 4 kexts to get control temperature of gpu, cpu etc. .working. Now on Niresh Yosemite 10.10 this method doesnt works, I've tried also to use MultiBeast installing HWMonitor, FakeMSC etc.. but nothing appaer

-on my PS/2 keyboard, if I press WINDOWS KEY + @ KEY, a "@" appaer on text box, but with USB Keyboard doesnt work, I cant write "@" and other many stuffs there is a fix to this, or a remap to use keyboard USB/PS2 as I use on Windows?

Thanks, sorry for long post, If you have only one solution, Can You help me to solve my problem? Thanks
